Earthquake Risk in Panama
Panama is not Chile or Mexico, but it holds a risk few countries do: an active fault that crosses one of the world's most important trade arteries. The Pedro Miguel fault runs through the Panama Canal at the Gaillard Cut and last ruptured around 1621, destroying old Panama City. The country's larger earthquakes come from its margins, the North Panama Deformed Belt on the Caribbean side and the Chiriqui zone on the Pacific, but it is the fault beside the Canal that makes Panamanian seismic risk a global supply-chain question as much as a local property one.

What drives the risk
Panama sits on its own small crustal block, squeezed by the convergence of the Caribbean, Cocos, Nazca and South American plates at around 25 millimetres a year. Two margins carry the largest earthquakes: the North Panama Deformed Belt, where the Caribbean plate underthrusts the block and generated the great 1882 event, and the Pacific Chiriqui zone in the west near Costa Rica, source of the 1934 and 2021 earthquakes. Through the centre of the isthmus, beside the capital and across the Canal, runs a system of strike-slip faults, Pedro Miguel and Limon, that accommodate the block's internal deformation.
Panama's largest earthquakes come from its edges. On the Caribbean side, the North Panama Deformed Belt is an active underthrusting zone assessed as capable of a magnitude 7.5 event; it produced the great 1882 San Blas earthquake, whose tsunami killed dozens and briefly halted French construction of the Canal. On the Pacific side, the Chiriqui margin in the west has generated repeated magnitude 6.5 to 7.7 events, including 1934 and the 2021 magnitude 6.7. Panama City itself sits away from these margins, at genuinely lower regional hazard than the coasts.
But the capital is not low-risk, because a crustal fault runs through the isthmus beside it. Peer-reviewed paleoseismology (Rockwell and colleagues, working for the Canal Authority) shows the Pedro Miguel fault crosses the Canal at the Gaillard Cut, ruptured around 1621 in an event compatible with roughly magnitude 7, offset the ground more than two metres where it crosses the waterway, and recurs on the order of every six hundred years. A rupture of the Pedro Miguel and neighbouring Limon faults is the near-field scenario for both Panama City and the Canal, and it is the reason the country's risk carries a weight out of proportion to its seismicity.

The Pedro Miguel fault and the Canal
The Pedro Miguel fault is a right-lateral strike-slip fault that crosses the Panama Canal at the Gaillard Cut and passes close to Panama City. Paleoseismic trenching by Rockwell and colleagues, carried out for the Canal Authority and published in the peer-reviewed literature, found three surface ruptures in the past 1,600 years, the most recent around 1621, when it partially destroyed old Panama City. That rupture offset the ground by more than two metres where the fault now crosses the waterway, and the average recurrence is on the order of six hundred years.
A repeat, of roughly magnitude 7 on the Pedro Miguel and neighbouring Limon faults, is the scenario that matters most, because it couples a shaking-and-surface-rupture hazard to Panama City with a hazard to the Canal itself, through which around 5% of global maritime trade passes. For a (re)insurer this is a business-interruption and accumulation question that reaches far beyond Panama's borders, and it is precisely the near-field geometry our model resolves.

Major historical earthquakes
The events that shaped how Panama is underwritten today.
| Year | Magnitude | Event | Impact |
|---|---|---|---|
| 2021 | M6.7 | Chiriqui earthquake Offshore western Panama | A magnitude 6.7 off the Chiriqui coast with no significant onshore damage: the Pacific margin's regular signature. |
| 1991 | M7.7 | Limon earthquake Costa Rica-Panama border / Bocas del Toro | Around 79 deaths in Panama's Bocas del Toro province, with coastal uplift, destroyed roads and a Caribbean tsunami. A North Panama Deformed Belt thrust event. |

| 1882 | M7.9 | San Blas earthquake and tsunami Caribbean coast | The great Caribbean-coast earthquake: around 250 dead, a three-metre tsunami on the San Blas islands, and a pause in French construction of the Canal. |
| 1621 | M7.0 | Pedro Miguel fault rupture Panama City / the Canal route | A rupture on the fault that now crosses the Canal, compatible with roughly magnitude 7, that partially destroyed old Panama City. The near-field reference event. |
The insurance market and the protection gap
Panama is a regional financial and insurance hub: a dollar-using economy with more than twenty insurers, a captive-insurance regime dating to 1996, and a banking centre that concentrates value in the capital. Insurance penetration is around 2.3% of GDP, with non-life the larger share. Banks require fire and allied-perils cover on mortgaged property, and the standard Panamanian fire policy bundles earthquake, so cover concentrates on financed and commercial property in Panama City and thins elsewhere.
No Panamanian earthquake has produced a documented material insured loss, a fact that reflects both the country's moderate seismicity away from the margins and the low penetration of the exposed residential stock. The catastrophe cash that has actually flowed has been parametric: Panama is a member of the CCRIF regional risk pool, where it holds excess-rainfall and earthquake policies, and it received a US$26.7 million rainfall payout in 2024. Sovereign protection is rounded out by a US$41 million World Bank catastrophe drawdown option and an Inter-American Development Bank contingent credit line.
For an international (re)insurer, Panama's interest is less its premium base than its exposure geometry. The near-field Pedro Miguel scenario places a moderate but concentrated hazard on the capital's banking real estate and on the Canal, an asset whose disruption is a global rather than a local event. That is an accumulation and business-interruption question that the country's own seismicity understates.
The Canal as a global accumulation
The Panama Canal carries around 5% of world maritime trade and a far larger share of United States east-coast and Asia routes; more than 14,000 vessels a year transit it. It contributes on the order of 4% of Panama's GDP directly and a larger share once its cluster and government dividends are counted. The Canal Authority appraises its locks, dams, power plants and structures for insurance and procures property cover, though its policy limits are not public.
The earthquake angle is specific. The Pedro Miguel fault crosses the waterway at the Gaillard Cut, and a rupture there would offset the ground by metres exactly where the Canal runs, with the potential to damage locks and disrupt the reservoir system that feeds them. A closure measured in months would ripple through global supply chains, a scenario public analyses of the Canal as a chokepoint already treat seriously for drought and congestion, and one that earthquake risk makes sharper. Underwriting Panamanian exposure without pricing this single fault understates the tail that matters most.
What it means for your book
For a (re)insurer, Panama is a concentration and business-interruption story, not a frequency one. The property tail sits in Panama City, exposed to the near-field Pedro Miguel fault and to the Caribbean and Pacific margins; the systemic tail sits in the Canal, whose disruption is a global supply-chain event. Both are questions of a few specific sources beside specific assets, which is exactly where a site-resolved model earns its place.
This is where the three Xpectral layers enter the book directly. Sismicus resolves the ground-shaking hazard at the site, from the deformed belts to the Pedro Miguel fault, on the model's own geometry. Fragility turns that shaking into a defensible loss for each asset, from banking towers to industrial and infrastructure risk. Risco converts the portfolio into the average annual loss, exceedance-probability curve and probable maximum loss that feed pricing, accumulation limits and Solvency II capital.
Frequently asked
Does an earthquake fault run through the Panama Canal?
Yes. Peer-reviewed paleoseismology, carried out for the Canal Authority by Rockwell and colleagues, shows the Pedro Miguel fault, a right-lateral strike-slip fault, crosses the Canal at the Gaillard Cut. It last ruptured around 1621 in an event compatible with roughly magnitude 7, offsetting the ground by more than two metres where it crosses the waterway, and it recurs on the order of every six hundred years.
How earthquake-prone is Panama?
Panama is moderately exposed. Its largest earthquakes come from its margins: the North Panama Deformed Belt on the Caribbean side, source of the great 1882 event, and the Chiriqui zone on the Pacific side in the west, source of the 1934 and 2021 earthquakes. Panama City sits at lower regional hazard than the coasts, but a crustal fault, Pedro Miguel, runs beside it and across the Canal.
What would an earthquake mean for the Panama Canal?
The Pedro Miguel fault crosses the Canal at the Gaillard Cut, so a rupture there would offset the ground by metres where the waterway runs, with the potential to damage locks and the reservoir system. Because the Canal carries around 5% of global maritime trade, a closure measured in months would be a global supply-chain event, making it an accumulation and business-interruption concern well beyond Panama.
Is earthquake insurance common in Panama?
Banks require fire and allied-perils cover on mortgaged property, and the standard Panamanian fire policy bundles earthquake, so cover concentrates on financed and commercial property in Panama City. Overall penetration is around 2.3% of GDP, and no Panamanian earthquake has produced a documented material insured loss, reflecting both moderate seismicity and thin residential take-up.
How is Panama protected against catastrophes at the sovereign level?
Panama is a member of the CCRIF regional catastrophe risk pool, where it holds excess-rainfall and earthquake policies, and it received a US$26.7 million rainfall payout in 2024. It also holds a US$41 million World Bank catastrophe deferred drawdown option and an Inter-American Development Bank contingent credit line.
